The EPC register is the official online database where you can find, check, and download Energy Performance Certificates (EPCs) for properties in England, Wales and Northern Ireland. It can help you understand a property’s energy efficiency rating, see estimated energy costs, and view recommendations for improvements.
EPC Certificates also has a register storing data on all EPCs issued in the last 15 years, resulting in millions of records, making it one of the largest energy databases in the UK alongside the government’s EPC register.
In this guide, we’ll explain exactly what the EPC register is, how you can use it to find and download EPCs, why EPC ratings matter if you’re selling or renting a property, and what the wider data can tell us about housing efficiency trends. You’ll also learn practical ways to improve your own EPC score and reduce energy costs.
Definition of EPC Register
The EPC register is the official government database managed by the Ministry of Housing, Communities & Local Government (MHCLG). You can access it online via the gov.uk website here.
The register exists to hold every Energy Performance Certificate (EPC) and Recommendation Report issued for properties in England, Wales, and Northern Ireland. Scotland has its own separate system.
Who manages it
The register is overseen by the UK government, and only accredited domestic or commercial energy assessors can lodge certificates in it. This ensures the information is accurate and consistent.
Why the EPC register exists
The EPC register was created to support energy efficiency regulations. Since 2007, you must have an EPC when selling or renting most properties. The database allows tenants, buyers, landlords, and regulators to check a property’s EPC rating quickly and transparently.
How to use the EPC register
Finding a property’s EPC with the EPC register
To find an EPC, simply enter the property’s address or Report Reference Number (RRN) into the EPC register search tool on gov.uk. If an EPC has been issued in the last 10 years, it should appear instantly.
The EPC Certificate register works in a similar way. You can enter any property address in the UK to see the EPC rating and information about improving its insulation, windows, heating, and other features.
Downloading EPCs
Each certificate can be downloaded for free as a PDF. It includes:
- Energy efficiency rating (A–G).
- Environmental impact rating (carbon emissions).
- Estimated energy costs for heating, lighting, and hot water.
- Recommendations for making the property more energy efficient.
Checking EPC expiry dates
An EPC is valid for 10 years. The register shows the issue date, which makes it easy to see if yours has expired. If you’re selling or renting again, you’ll need to renew before marketing the property.
Why EPCs matter
EPCs aren’t just a piece of paper; they’re a legal requirement when selling, renting, or building in England, Wales, or Northern Ireland. Landlords must also provide a valid EPC to tenants at the start of a tenancy.
Legal requirement when selling/renting
Failing to have a valid EPC can result in a fine. For domestic dwellings, the penalty is usually £200, while non-compliance for commercial properties can be higher.
How EPC ratings affect property value and energy costs
- Potential buyers and tenants now check EPC ratings to estimate running costs. A better EPC can make your property more attractive.
- Research shows that homes with higher EPC ratings often sell faster and at a premium compared to those rated F or G.
- A poor rating suggests high energy bills and may put off buyers.
EPC register data and trends
The EPC register is extremely useful for individual property checks. In addition, it provides insights into housing stock across the UK.
Average ratings over time
Since EPCs were first introduced, the average UK rating has improved from E/D to a solid C. This reflects increased awareness of insulation, better boilers, and stricter building regulations.
Regional trends in the EPC register
Data shows variations across regions. Homes in London and the South East tend to score better due to newer builds. Meanwhile, properties in Wales and Northern Ireland often rate lower, with more older housing stock.
Impact of regulations
Government schemes such as the Minimum Energy Efficiency Standards (MEES) for landlords have pushed rental properties towards higher EPC ratings. This trend is likely to continue as efficiency standards tighten.
How to improve your EPC rating
If your EPC score is lower than you’d like, there are practical steps you can take.
Quick wins
- Install LED lighting throughout your home.
- Draught-proofing and loft insulation can make a big difference.
- Upgrade your boiler controls or add smart thermostats.
Long-term measures
- Cavity wall or solid wall insulation to reduce heat loss.
- Renewable heating systems, such as heat pumps.
- Solar panels to reduce electricity costs and carbon emissions.
These improvements don’t just raise your EPC rating; they cut your bills and make your property more comfortable year-round.
Common questions about the EPC register
Do all properties need an EPC?
Most properties need an EPC, but there are exemptions. For instance, listed buildings, temporary buildings, and some industrial sites may not need one.
How long is it valid for?
An EPC lasts for 10 years, after which a new assessment is required.
How much does it cost to get one?
Domestic EPCs usually cost £40–£120, depending on property size and location. Commercial EPCs are more expensive due to the complexity of the assessment.
EPC registration
The EPC register is a vital tool for buyers, tenants, landlords, and developers. It provides a transparent record of how energy efficient a property is and highlights practical ways to reduce energy costs.
You can access the register directly on gov.uk, but if you’re looking to go beyond the certificate and actually improve your EPC rating, you’ll need professional help.
